Chapter 1 General
Article 1.0.1 In order to ensure that the architectural design of cinemas meets the basic requirements of safety, hygiene and functional use, this specification is specially formulated. Article 1.0.2 This specification applies to the architectural design of newly built, expanded and renovated cinemas that mainly project 35mm anamorphic, masking wide screen and ordinary screen (including stereo) films.
Other public gatherings and entertainment performance buildings that also project movies and have fixed projection equipment can refer to the relevant provisions of this specification for implementation.
Article 1.0.3 The scale of cinemas can be divided into: extra large with more than 1,201 seats;
large with 801 to 1,200 seats;
501 to 800 seats;
small with less than 500 seats.
Cinemas should be reasonably distributed and of appropriate size. When the total scale of cinemas is large, it is advisable to set up multiple auditoriums.
Article 1.0.4 The quality standards of cinemas are divided into four grades: special, A, B, and C (cross-combined with extra large, large, medium, and small). The requirements of special grade are determined according to specific circumstances. The corresponding requirements of A, VII, and C grades should comply with the following provisions: 1. Durability of the main structure: A grade is more than 100 years, B grade is 50 to 100 years, and C grade is 25 to 50 years.
Above, fire resistance grade, A and B grades should not be lower than level 2, C grade should not be lower, and there should be no extra large.
3. Audiovisual facilities: Stereo sound is recommended for Class A. The main structure of a Class A or larger auditorium should be able to play, or be rebuilt to play, 70mm films. Www.bzxZ.net
Note: For the basic civil engineering conditions for the auditorium to play 70mm films, see Appendix 1. Engineering Construction Standard Full Text Information System
